Design and implementation of simple fuzzy logic controller (SFLC) for the voltage control of resonant converter

In this paper a simple fuzzy logic controller (SFLC) is presented for voltage regulation of extended period zero current switching quasi resonant (EP-ZCS-QR) buck-boost converter. The effectiveness of the proposed controller is verified for load variations and supply disturbances in experimental set up using TMS320C2407 processor. The experimental results obtained by implementing conventional fuzzy logic controller (FLC) and the proposed methods are compared. It is proved that the proposed method reduces the complexity in hardware implementation and produces better results compared to the conventional FLC.
